Howard Jacobson just won the Man Booker Prize with his novel, The Finkler Question. The main talking point of this event is the fact that it’s the first comic novel to win the prize in its 42-year history.

When I think of comedy fiction, three writers come to mind – Robert Rankin, Terry Pratchett and Douglas Adams. For me the first two – and I love Robert Rankin, and am on the positive side of indifferent to Terry Pratchett (it’s just been announced that Pratchett is a World Fantasy Lifetime Achievement Award winner) – are fairly self-indulgent reads. People read Rankin and Pratchett because there’s something comforting about the worlds they’ve created and sustained in the five million novels they’ve written between them (five million is an approximate figure). They are full of wordplay, silliness and running gags. Douglas Adams, for me, is a much more serious writer. When I read the Hitchhiker books I get a sense of existential melancholy; that series explores the fundamental pointlessness of human existence. The answer to the question – the question, about life, the universe and things of that nature generally – is 42 – which is about as meaningful as any other answer people have come up with.

Jacobson’s thesis, from what I’ve read and heard in the past day, is that comic novels are not or should not be a minor sub-genre, but the totality of literature – all novels should make you laugh, he says.

Well, I would say that humour is a useful tool in any writer’s kit – any novel can have flashes of humour that arise from the characters or the situations. But comic writers also use a certain voice – an authorial voice that is itself humorous, witty, punning, observational – that doesn’t often sit well with literary quality. Of the three writers I mentioned, I would say Adams achieves it, but Rankin and Pratchett do not.

It would be nice to think that all writing and writers are published simply for their literary merits, but it seems like the reality is that many books are published because they fulfil(publishing companies’ perception of) market demand. Fantasy novels have to be about 8,000 pages long and tell the story of a young hero, or group of young heroes, in excrucating detail from childhood to confrontation with the ultimate evil that killed their parents. And comedy novels, clearly, can’t be serious literature – it would confuse people.

My favourite series of books is Stephen R Donaldson’s Gap series. It’s a gripping, brutal space opera – but it has one joke (if that’s the right word) that stood out for me. Introducing one character, Godsen Frik, the book says something along the lines of, ‘He had the fleshy smile of a pederast who’d just been made the head of a boys reform school.’ Appropriately dark, but in as much as it is funny (opinions may differ), it’s somehow out of keeping with the tone of the rest of the story.

I think, ultimately, that each book should just be good at was it does, whether it’s a comedy, a funny book with serious bits, a serious book with funny bits or a work of unleavened humourlessness.

I’ve never read any Howard Jacobson, although I’ve seen him in the media over the years and he’s always seemed plain-speaking and likeable. I should get a copy of one of his books at some point – maybe even The Finkler Question. You can read more about him and his shiny new 50,000 pound prize on the Independent website or over at the Telegraph – or any other news site (but you’ll have to search for them yourself).
